ADJUSTABLE BRACKET.

Specification of Letters Patent.

Patented. Jan. 1, 1907.

Application filed May 29.1906. Serial No. 319,380.

' of Indiana, have invented new and useful Improvements in AdjustableBrackets, of which the following is a specification.

This invention relates to a bracket, and is more particularly adaptedfor suspending electric lamps of the arc-light type, though it isapplicable to any use to which a bracket may be applied.

The object of the invention is to provide a bracket that may be adjustedso as to change the angle of the brace member relative to the supportingmember, and thereby regulate the stresses or pulls on the attachingdevices.

With these and other objects in view the invention consists in theconstruction, com bination, and operative aggroupment of all as will bemore fully described hereinafter, illustrated in the accompanyingdrawings, and finally pointed out in the appended claims.

.In the drawmgs, Figure 1 is a perspective view of one form of thebracket shown attached to a wall. Fig. 2 is a similar view of anotherform. Fig. 3 is a perspective view of another form, showing thesupporting member of the bracket secured to aprojecting portion of awall and the brace member secured to the wall in a plane in the rear ofthe plane of the projection; and Fig. 4 is a detail in longitudinalsection through a portion of the supporting member, the strut member,and the clamping members shown in Fig. 3.

In carrying out my invention I aim to provide an extremely inexpensiveand strong bracket and one that may be adjusted to fit in any-sizerecess of a wall or to a wall of irregular contour, and to these endsthe invention primarily consists of three elementsa supporting-bar 5, abrace 6, and a strut 7.

The supporting-bar 5 is adapted to have one end attached to a wall, asat 8, and its other end formed into a hook or eye 9, on which may beengaged the insulator of an electric-arc lamp or any other suitableobject that it is desirable to suspend. The brace or bar 6 is adapted tohave one end attached to the wall, as at 11, and its other end isattached to the supporting-bar 5 near the outer free end thereof, as at12.

While I term the bar bar and the bar 6 the both, in fact,supporting-bars; but this no- 5 the supportingbrace, they arelmenclature is employedfor the purpose of distinguishing one from theother, and while these bars are of comparatively rigid mate rial, beingmade of metal, they are flexible enough to permit their attaching ends 8and 11 to be spread apart or brought near to gether without affectingthe fastening 12 at r the free ends of the bars, and when once adjustedto the proper position they may be so held or clamped by means ofclamping members 13 and the strut member 7.

The strut member consists of a metal bar preferably bent so as to haveits ends disposed parallel with the supporting and brace bars, and inorder that some portion of the bent end will always be disposed parallelto the supporting'and brace bars notwithstanding the adjustment of thelatter the strut is preferably bent into S shape, so that its ends aredisposed inthe arc of a circle. Thus when the inner ends of thesupporting and brace bars are brought shown in Fig. 1, the strut member7 is positioned near to said ends of the supporting and brace bars andpreferably at an inclination to the wall, as shown in Figs. 1 and 2. Thestrut member is held in position by means ofclamps 13, which consist ofloops or rings slidably mounted upon the supporting and brace bars andalso upon the strut member, which, by virtue of its peculiar shape, ismore or less resilient, and thus permitted to be frictionally clamped tothe supporting and brace bars by loops. In some instances it may bedesirable to employ an additional strut member, one of which is shown inFig. '1 at 14 in the form of a ring clamped to the supporting and bracebars by additional loops 13.

In Fig. 2 the strut member 7 is shown arranged at the opposite inclineto that shown in Fig. 1, in which position it will better serve thepurpose of keeping the members separated and receive the compressionstrain; but

I in every instance this strut serves to equalize the strains upon thebracket and transmits tensile strain from the supporting-bar 5 to thebrace-bar 6, which, with the strut, receives the compression strains.

In Fig. 3 the ends of the supporting and brace bars are shown attachedto a wall whose vertical face is shown in different planes, and while inthis instance it is not absolutely necessary that the inner ends of thesupporting and brace bars be separated to any great extent they areshown so in the near together, as

, ends, and a strut member adjustably mounted'between the supporting andbrace bars.

2. A bracket comprising an upper supp orting-bar and a lower braceconnected at its outer end to the outer end of the supportingbar andarranged at an angle thereto, a strut drawings to illustrate theadjustability of the i apart at their inner bracket, and of course whenso adjustedthe l strut member 7 is moved to near the outer i ends of thesupporting and brace bars and suitably clamped, as shown.

In the event that the curvature of the ends 2 and the inclination of thestrut member are 1 not suflicient to cause a frictional bindingengagement of the latter with the supporting and brace bars I may employadditional clamping members 15. (Shown in Figs. 2 and 3.) These consistof fiat bars, one end of which is wedge-shaped and the other end ofwhich is formed into an eye or loop, which not only adds to theornamental character of the bracket, but also serves as a handle or as asurface with which a hanger may be en- 'aged. When these wedges 15 areutilized or clamping the strut member invposition, the wedge-shaped endsare adapted to fit in between the outer parts of the clampingloops l3and the outer faces of the bars 5 and 6, as shown in Fig. 3; but whennot utilized as clamps they may be positioned on the bars I at any pointto serve as ornamental scrolls.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

1. A bracket comprising a supporting-bar,

with the supporting and brace bars, and clamping members for connectingthe ends of the strut member with the supporting and brace bars.-

3. A bracket comprising two bars connected together at their outer endsand disconnected at their inner ends, a strut member, loops slidablymounted upon said bars and connected with the strut member, and wedgesfor clamping the strut member, the loop and the bars together. i

4. A bracket comprising a supporting-bar, a brace-bar, said bars beingconnected together at their outer ends and adapted to be broughttogether or spread apart at their inner ends, and a pair of strutmembers adjustably mounted between the supporting and brace bars.

In testimony whereof I affix my signature in presenceof two subscribingWitnesses.
